Is item information not available on an advanced PDF of a picking ticket???? Is that why its greyed out?

You should be able to access the item sublist by coding it.

What do you mean by this?

I wouldn't trust the WYSIWYG editor there. I can confirm I'm using the same pattern (

#list record.item as item

), which is working. However, I will say that for some reason we're using a Packing Slip template to print our picking tickets, not sure if that is important (I think it's because Packing Slip templates have access to the

salesorder

record, whereas Picking Ticket don't)

@David B That sounds like it might be my issue, but I don't understand how you use one template to print a different thing? Where are you given that option?

Looks like we've renamed the native "Print Packing Slip" to "Print Picking Ticket". And we've then added a custom button to print with another packing slip PDF.. EDIT: again, not sure if we're using Packing Slip template instead of Picking Ticket template because of similar issues to you

@Azi Did you select the custom picking ticket form on the Sales Order form?
